American Pacific coast waters prior to 1957 

 were of subnormal temperatures; 1957 began a 

 period of warming lasting through at least 

 1959. Many southern marine species appeared 

 north of their usual range and some spawned 

 off southern California. Similar species 

 intrusions were recorded in the past. He 

 listed several abnormal northward occurrences 

 of marine mammals and other biological ano- 

 malies.

A history of references to anomalous fish 

 distributions off California and speculations 

 on environmental causes. He argued for a 

 direct relation between temperature and fish 

 distribution rather than temperature as an 

 index of other factors.

 oxygen in the summer thermocline. J. Mar. Res. 

 20:138-148. 



A summer subsurface maximum in oxygen oc- 

 curred which was in excess of surface values 

 by over 1 ml per liter. Seasonal variations 

 in temperature accounted for the formation of 

 the subsurface maximum in summer. 



KEY WORDS: oceanography, oxygen, depth, 

 thermocline, temperature, season.
